1 isn't considered a prime number so three can't ve constructed from just primes
It says even number though
Yes, but keep in mind:
I can't read
Touché
4 then - if 1 isn't a prime, then 1+4 doesn't count.
EDIT - should have been 1+3, doh!
2+2
Jesus, I forgot 2 was a prime, what a dolt.
1+4=5 not 4 and 4 isn't prime either, so idk what you meant. 4 is the sum of two primes 2+2, which I thought was what you were asking at first.
I screwed up twice here. Forgot 2 was a prime somehow.
1+4 was just a typo, meant 1+3.
1+4 is 5 though.
Yeah, typo. But I was wrong anyway! :-)
I am disappointed in Lemmings' collective lack of Savvy regarding math trivia.
Next thing you'll be telling me you don't know how to prove there's an infinite number of prime twins.
